Method Detail

addColorStopRGB

public void addColorStopRGB(double offset,
                            double red,
                            double green,
                            double blue)

Add a colour stop to a Pattern gradient. Equivalent to calling:

 addColorStopRGBA(offset, red, green, blue, 1.0);

See addColorStopRGBA() for documentation of the offset parameter. The colour parameters are the same as for setSource().

Since:: 4.0.7

addColorStopRGBA

public void addColorStopRGBA(double offset,
                             double red,
                             double green,
                             double blue,
                             double alpha)

Add a colour stop to a Pattern gradient.

The offset parameter provides for the ordering of stops. When a Pattern applies its colour stops, it works through them in the order specified. If two stops are specified with identical offset values, they will be sorted according to the order in which the stops are added, is used for making sharp color transitions instead of a blend.

Colour stops handle colour arguments the same way as setSource() does.

Since:: 4.0.7

getSurface

public Surface getSurface()

Get the Surface backing this Pattern. Obviously this only works with SurfacePatterns.

Since:: 4.0.18

setExtend

public void setExtend(Extend extend)

Specify the strategy to be used when drawing the pattern outside of the area implicit in the how the Pattern itself is described.

If you're looking at this, it's probably because you're wondering why your Pattern isn't extending. Call this with REPEAT.

Since:: 4.0.17
